Loop内部的Shuffle值和与数组连接

我确实需要在数组内部我需要对值进行随机化。

以下是代码段

$vehicle = array('hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv');
$RequiredVehicle = 3;

$vehicleList = array();


for($i=0;$i<count($vehicle);$i++)
{
  $vehicleList[] =$vehicle[$i].$RequiredVehicle;
}

echo "<pre>";
print_r($vehicleList);

我得到的输出是

Array
(
    [0] => hcv3
    [1] => hcv3
    [2] => hcv3
    [3] => hcv3
    [4] => hcv3
    [5] => hcv3
    [6] => hcv3
    [7] => hcv3
    [8] => hcv3
    [9] => hcv3
)

我需要的实际输出是

Array
(
    [0] => hcv1
    [1] => hcv2
    [2] => hcv3
    [3] => hcv1
    [4] => hcv2
    [5] => hcv3
    [6] => hcv1
    [7] => hcv2
    [8] => hcv3
    [9] => hcv1
)

10 车辆和 3 所需车辆所以我需要的输出是总车辆应该在3辆所需车辆之间洗牌

如果$ vehicle = 10且$ RequiredVehicle = 3那么Array值应为 的 1,2,3,1,2,3,1,2,3,1

如果$ vehicle = 10且$ RequiredVehicle = 2,那么Array值应为 的 1,2,1,2,1,2,1,2,1,2

这是因为您只是追加$RequiredVehicle

您可以使用%$i并添加1.赞( ( $i % $RequiredVehicle ) + 1 )

$vehicle = array('hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv');
$RequiredVehicle = 3;

$vehicleList = array();
for($i=0;$i<count($vehicle);$i++)
{
   $vehicleList[] =$vehicle[$i] . ( ( $i % $RequiredVehicle ) + 1 );
}

echo "<pre>";
print_r($vehicleList);

这将导致:

Array
(
    [0] => hcv1
    [1] => hcv2
    [2] => hcv3
    [3] => hcv1
    [4] => hcv2
    [5] => hcv3
    [6] => hcv1
    [7] => hcv2
    [8] => hcv3
    [9] => hcv1
)

希望它能提供你的实际输出:)

 $vehicle = array('hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv','hcv');
$RequiredVehicle = 3;

$vehicleList = array();

$j = 1 ;
for($i=0;$i<count($vehicle);$i++)
{

  $vehicleList[] =$vehicle[$i].$j++;
  if($j > $RequiredVehicle){
     $j=1;
}
}

echo "<pre>";
print_r($vehicleList);

输出:

Array
(
    [0] => hcv1
    [1] => hcv2
    [2] => hcv3
    [3] => hcv1
    [4] => hcv2
    [5] => hcv3
    [6] => hcv1
    [7] => hcv2
    [8] => hcv3
    [9] => hcv1
)
